Title: Error protection for multi-pulse speech coders
Inventor: ZINSER RICHARD LOUIS
IPC: H04L1/00
Filed: 1990-11-21
Abstract: A low overhead method of protecting multi-pulse speech coders from the effects of severe random or fading pattern bit errors combines a standard error correcting code (convolutional rate 1/2 coding and Viterbi trellis decoding) for protection in random errors with cyclic redundancy code (CRC) error detection for fading errors. Compensation for detected fading errors takes place within the speech coder. Protection is applied only to the perceptually significant bits in the transmitted frame. <IMAGE>

IPC: A01G9/10
Filed: 1992-05-11
Abstract: A multi-cell plant container 11 is moulded from a single sheet of material and defines a label panel 21 which bridges two cells 20 of the container.

Access may be gained to those label panels of a number of supported containers, for the placement thereon of self-adhesive labels by automatic machinery, during loading of the container cells with growing medium and seeds or plants. <IMAGE>
Patent GB-2257181-A (GB)
Title: Temperature-compensated drill stem test tools
Inventor: JOHNS RAY
IPC: E21B34/10
Filed: 1992-05-29
Abstract: The various tools included in a downhole test string are controlled by changes in the pressure differential between the annulus and a fixed "reference" pressure within the tool. Reference pressure within the test string is trapped by a mechanism wherein a valve (4) drivable into a closed position by a first piston (3) open (at 5) to annulus pressure first defines, and then defines and closes, the open-to-tubing-pressure entrance (6) to a passageway (30/19) leading to a reference-gas-containing chamber (22) via a second piston (20) therewithin. The invention proposes a mechanism by which compensation can be made for the effect of downhole temperature changes on the gas in such a reference pressure chamber, in which mechanism there is a hydraulic-liquid-containing chamber (27) which is connected at one end, via a piston (25) thereat, to a vent (24) to annulus and at the other end to two "one-way" passageways (28, 29) linking it to the reference-gas-containing chamber (22) via a chamber-contained second piston (23). <IMAGE>

Abstract: The invention provides and extends earlier inventions to provide a means of installing, buoyancy and thermal insulation of submarine pipelines and equipment, by containing a pipeline or group of pipelines, object or structure within a single or group of elongate jackets filled with hollow spherical material. The composite assemblage of jacket, hollow material and structure or objects within it, exhibits compliant behaviour, deriving increased mechanical strength, impact resistance and resistance to hydrostatic collapse. More particularly, this invention provides means by which the compliant strength and mechanical durability are further enhanced. Microspheres and bonding liquid are mixed before being introduced into the cavity between the jacket 4, 5 and around the pipe or group of pipes 1, 2. The internal surface of the jackets 4, 5 may be grooved, routed or roughened. An adhesion layer may be applied to the internal and/or external surface of jackets 4, 5. <IMAGE>

Title: Intelligent signal processing
Inventor: SINERNS THOMAS MICHAEL
IPC: G08C15/12
Filed: 1992-12-14
Abstract: Intelligent signal processing circuits typically involve complex circuitry with large numbers of wire interconnections and tend to have high power requirements. An intelligent digital signal processing circuit is proposed which comprises: a) a digital signal processor (DSP); b) the interfacing of a plurality of serial data channels to the DSP with each channel being capable of converting a received analogue signal to a digital signal; c) a power supply for each channel where the power supply is modulated by a common clock signal and each channel possesses means to separate the clock signal from the power supply. For the purposes of data transmission wiring can be limited to 3 wires per channel, one for serial data, one for power and a timed pulse to synchronise data transmission and one as an earth return. Circuits produced according to the invention can handle multiple signals, real-time signal processing of incoming signals and the output of filtered signals in digitally multiplexed format.

Filed: 1993-02-24
Abstract: In a method for forming a shallow ohmic contact (21, 23) to a buried layer 3 of a semiconductor heterojunction device 1, an interface 11 which presents an abrupt energy barrier is disrupted in the region of desired contact by implanting ions at an appropriate energy. This results in compositional intermixing of the interface. The ohmic contact is then completed by diffusing a high concentration of dopant. <IMAGE>

Title: Avoiding the effects of misregistration in producing colour separations
Inventor: MALONE DAVID
IPC: H04N1/58
Filed: 1993-03-24
Abstract: An original keyline image is scanned by raster scanner 2 and the resulting data is used to generate a high resolution keyline file and a separate low resolution raster file. The raster file is coloured in by an image processor 5. A computer 6 carries out post-processing of raster file by identifying keyline pixel fields, amending the data in these fields so that the colour of a keyline pixel is the same as that of the nearest pixel bordering on the keyline. This generally involves changing the colour separation value from 0 to the relevant value. An imagesetter 7 then exposes a film for the high resolution keyline file, and a set of file colour separation films, one for each of the colour separations. When these are superimposed the colour separations overlap onto the keylines so that any mis-registration in the printing process is compensated for. <IMAGE>

Title: Polarized light microscopy
Inventor: LAWRENCE MICHAEL

Filed: 1993-09-09
Abstract: In the study of living organisms using a polarizing microscope, a compensatory wave-plate 18, e.g. a birefringent crystal, is positioned between a polarizer 14 and a sample object 10 on the one hand and an analyzer 16 on the other hand. The system is set up to establish interference colours.

Images can be obtained of entire, living, moving organisms. The wave-plate 18 is set at a small angle, between 2 DEG  and 15 DEG , to the polarizer and/or analyzer. <IMAGE>
Patent GB-2282287-A (GB)
Title: Mixers
Inventor: MURTOJARVI SIMO
IPC: H03C1/54
Filed: 1993-09-25
Abstract: The frequency band of an I/Q diode modulator is expanded by adding two capacitors (15, 16) and an inductance (17), or two inductances and one capacitance, respectively. The capacitors (15, 16) are connected in series and have a zero voltage at their connection point so that the inductance (17) does not influence the local oscillator signal Lo. When the diodes (4, 5) are set to be conductive, the voltage at the point between the diodes (4, 5) is connected to both branches of the transformer (8) secondary so that the branches have equal voltages with the same phase. The inductance (17) is dimensioned so as to form a series resonance together with the capacitors (15, 16) at the frequency at which leakage between nodes 18, 19 causing undesirable mixing because of the capacitance of the diodes (4, 5) would otherwise occur. In this way, the impedance between ground and the diode (4, 5) connection point is very low and so is the leakage between the mixer outputs at 18, 19. The invention enables realizing an 110 modulator or demodulator for 400 MHz or even 900 MHz frequencies with ordinary UHF mixer diodes. FETs may be used in place of diodes and the elements 15 - 17 may be formed by stripline or microstripline components. <IMAGE>

Title: Obtaining soils and fertilizers from sludge
Inventor: BURNHAM JEFFREY C
IPC: C02F11/12
Filed: 1994-12-21
Abstract: A dewatered raw sludge or pasteurized or sterilized sludge when still in a wet condition or when dry is mixed with specified alkaline adsorptive materials and is adjusted to a mildly alkaline pH, and to an ionic conductivity which will allow the sludge to mature rapidly when seeded with a beneficiating microbial flora. This process will reduce the pH of a high alkaline treated sludge, e.g., often above pH 12, to a physiological pH of between 7 and 9.5 or will raise the pH of a treated acid sludge to a similar range so that microbial activity can proceed to facilitate stability. Heat may be applied to the mixture to accelerate carbonation and aid the overall drying process. The granular product is useful as an agricultural product and topsoil blend. The sludge may be a wastewater sludge or a bioorganic or organic sludge e.g. a mycelial or bacterial product residue or recycled paper residue.
